    • ASTM D5334 Thermal Resistivity Testing, Thermal Dryout Curve

      The thermal dryout curve (thermal resistivity vs. water content relationship) is determined on a customer-supplied sample.  ASTM Test Method D5334 thermal resistivity measurements are made at the as-found water content, saturated, and oven-dry conditions at room temperature.  The thermal dryout curve is interpolated using the combination method described here.

      A brief report describing the test method, thermal dryout curve, and sample dry bulk density is emailed to the customer within 15 working days of sample receipt at METER.   Testing and delivery of results can be expedited for a fee.

      Soil samples should be tightly confined in rigid containers to preserve desired bulk density.  Minimum sample size is 4 cm diameter X 10 cm length.

      Sample size is dependent on the thermal properties of the material being tested. In general a 2cm radius of sample material around the needle(s) is sufficient for samples with thermal conductivities around 0.5 W/mK. Samples with lower conductivity (i.e. insulation) can be tested with a smaller sample size. Samples with a higher conductivity (i.e. granite) will require a larger sample to avoid boundary effects.

      See Instructions for collecting samples for thermal analysis.

    • ASTM D5334 Thermal resistivity testing, as-received plus oven dry

      The thermal resistivity/conductivity of a customer-supplied sample is measured at the moisture and density conditions at which the sample is received, and at the oven dry condition to characterize the worst-case thermal scenario.

      Measurements are made at three locations in the sample at room temperature and are conducted in accordance to ASTM Test Method D5334.  A brief report describing the test method, thermal resistivity test results, sample as-received volumetric water content and sample dry bulk density is emailed to the customer within 15 working days of sample receipt at METER. Testing and delivery of results can be expedited for a fee.

    • Thermal Sample Volumetric Water Content and Dry Bulk Density Measurement

      The volumetric water content and dry bulk density of a soil/concrete/grout sample is determined in the state at which the sample is received at METER.  This service is offered as an addition to service ASTM D5334 soil/concrete/grout thermal resistivity testing, as-received density and water content, and the sample should be shipped as outlined in the description of that service.  Note that this service does not include manipulating the sample to a prescribed water content or density.

      Sample size is dependent on the thermal properties of the material being tested. In general a 2cm radius of sample material around the needle(s) is sufficient for samples with thermal conductivities around 0.5 W/mK.

    • Fluid Thermal Conductivity Testing

      The thermal conductivity is determined on a customer-supplied fluid sample in the as-received condition using the transient heated needle method. All measurements are made at room temperature, but sample temperature control is available for an additional fee.

      A brief report describing the test method and results is emailed to the customer within 15 working days of sample receipt at METER.  Testing and delivery of results can be expedited for a fee.

      Minimum sample volume is approximately 50 mL. Note that fluids with lower viscosity (thinner) than water cannot be measured reliably, and that the maximum test temperature is limited in most samples.  Please contact METER to discuss measurement limitations.

    • Material Thermal Conductivity Testing

      The thermal conductivity is determined on a customer-supplied sample in accordance with standard testing protocols.  All measurements are made in triplicate at room temperature, but sample temperature control is available for an additional fee.  A brief report describing the test method and results is emailed to the customer within 15 working days of sample receipt at METER.  Testing and delivery of results can be expedited for a fee.

      Note that the sample needs to be at least 10 cm in length,  4 cm in diameter, and soft enough for direct sensor insertion or able to be drilled with a 2.4 mm diameter X 10 cm long hole.  Please contact METER to discuss size and material limitations.
